I'm sorry if this has been posted before, but I'm in a big hurry and I need a pretty quick answer: I have to make a project for school which consists of many BASH scripts. At school we have Sun Sparcs. During the laboratory hours I used to open the text editor (in the graphics interface), edit the script then run it from terminal. But now I must connect from home to the server and do everything from the command line. I don't know anything about text mode text editors and I don't have the time to read through their manuals. I just need a quick how-to write something in a text editor and how to save it and exit the text editor, so then I can run that script.

I'm not sure if this qualifies as a homework question- i don't think it does so I'll post a reply.

Read the first few paragraphs of this vi tutorial and you will have the simple commands you need.

You may also try pico or nano if they're installed. They are very basic (and far inferior to my favourite vi), but they are simple to use, and if you're in a rush should get the work done. Most newer GNU/Linux systems (you're using bash, so I assume Linux here....) will have these editors.

I strongly suggest you to learn the VI editor.
VI it's a "must know" for all Unix users.
It works on all Unix and Linux vendors.
Have a look at this link for a list of VI commands:

http://www.chem.brown.edu/instructions/vi.html

The documentation is also available by typing
man vi
at the shell prompt

Thanks guys. I found PICO to be the simplest of all. I'll learn Vi if I'll continue to use UNIX, but for now that's just what I need. I'm running Solaris by the way.
